That wall co striction don't really add much to the cos for the benefit it offers.
Since you are sheathing the exterior, were you planning on making the 2x4's flush, or just nailed to the outside like typical?
Cause if just nailed outside, you will need about double the 2x4's if you plan on more than 1.5" insulation.
6" may sound like overkill, but there isn't a whole tone of price difference between 2 x 4 and 2x6, nor is there much price difference between r 13 and r19. If you plan to heat and cool, spending more on insulation is never a waste or never overkill.
Plus you can sheath the inside, since it will be flush, and you won't even see the posts. Neat, clean, efficient.
Price it all both ways. Wall lumber is a small drop in the bucket when you look at things in whole. On a 40*72 building like mine, with close to $30k spent, the difference between r13/2x4 vs r19/2x6 is probably less than a grand. So spending g very little additional is well worth the end benefits
